the' rods 15; between which are hinged the upper ends of the leaves 1thelower vends, of the leaves being hinged to he ioor of the:

vfeed-box. VThese leaves are spaced aparta distance slightly greaterthan the diameter' of a shell. The floor of the feed-box has thetransverse grooves 22, there being a groove beneath adjacent leaves. Thefront ends of the rods 15 are comiected'by a cross bar 17, through anorifice in which extends the camrod 18. This cain -rod is guided in thebrackets 19 secured to the feed box and is pivoted at one end to a crankpin on adisk 20 secured to a shaft 2 1 driven from a suit' able sourceof power. The spring 180 connects a projection on the cam-rod with afixed point on one of the brackets 19 and has for its` function to takeup lost motion be'- tweeii the cani-rod and its actuating mechanism.

In the rotation of the shaft 21, the eam- V rod 18 isverticallyreciprocated. thereby rcthe conveyer for carrying the shellsto the shuttles-` and properly distributing them Extending into ythegrooves 22 are the 80 lower arms vof the T-sliaped ej'ecting bars- 23,whose rear ends are secured to a/cross-` head 25 slidable back and forthwithin the. casing 24.

By sliding the cross-head 25 forwardly, 85'- tlie ejectors engage thealower tier of shells and push them forwardly through an opent-l ing atthe `front of the feed-box onto one of into position to be ejected assoon as the ejectors havev returned to vtheir rearward position.

The carriers 26 are shown in detail in Figs: 7 and 8. trunnion 27 issupported at opposite endsnon pins 28 on the sprocket chains 29. Thetrunnion 27 has the two downwardly projecting arms 30 connected togetherby the orificed bar 31, and the two connected by bars 33. The receivingplate" 34 of the carrier is provided with transverse grooves'corresponding in numbery to the groove-s 22 of the feed box, soA thateach shell, as it is dell'. ired from the feed-box tothe carrier isdeposited inaY definite posi-A tion. The receiver 34 1s removablysecured to the bars 33 by means of spring arms35 hinged centrally tothetop-plate and extending underlthe bars 33. Vhen it` is de sired toremove thereceiver, the spring-arms 35 are turned from under the bars33. The

bars 31 are orificed to receiveplugs 36, which may be distributedm saldorifices 1n suchmanner'as will secure as near as possible an'even-d1str1but1on of the weight and perfect balancmg.

' .The sprocket chams 29'for-dr1v1ng the carrier engage thesprocketwheels 38 and 39,

the lower wheels 38 being the driving wheels,

which are actuated intermittently, as hereing too far in the oppositedirection-by con- .tact of the pins 39 with the cams 41 secured inafterdescribed,- to advance the carriers 26,

after each feeding operatioin a distanceequal tothe space bet-Weenadjacent carriers, thereby presenting a fresh carrier into ositiontoreceive the neXt tier of shells ischarged' from the feed boX by theej-ectors 23.' Asthe loaded carriers are carried upwardly from the feedbox, they are tilted, one by one, to discharge 'their contents into aninclined conveyer, hereinafter described,

Which conveys them to a shell-holder or shuttle-feeder and at' the sametime distributes them soas to present them to the shuttle-feeder'inroper order and arrangement, as hereina ter described. l

The carriers are normally held by gravity lin the position in which allof them save one are shown in Fig. 1. Tof cause a carrier to tiltA anddischarge the shell when' it arrives opposite the conveyer, I providepins 39 at the lower end of each carrier, which pins,

when the carrier- 'reaches the eonveyer, en v gage cams 40 on themachine frame, which cams, as the carrler continues its movementJ tiltthe carrier into the` position shown in Fig. 1.` lVhen the pinpasses..beyond'.the cam, the carrier is prevented from swmgto th mainfram'ebeneaththe cams 40. A

The receiving end of the conveye'r, shown -in detail in Fig. 5,comprises an open-ended casing 42 whoseA bottom is-provided withcorresponding in number to the f the receiving plate ,34 of the Thecasing `is supported by 4ugs 43 socketed in brackets on the Extendingdownwardly .and

means@v 4ame.

. shell receptacles 46 in the shell-holder or shuttle-feeder`45. Theforward wall ofthe \,c:1sing 42 entends` downward vinthe formv of anapron, terminating inguards 420 which overlie lthe respective ways 44and lconfine' -the shells to theways.` -The upper ends of the ways areopen-topped, while 4the lowers beyond the guards 4204are of tubularform. The lower ends 0f the wa'ys 44 are supported from the frame byextension 430. The

ly are-ways 44 registering with the shuttle-feeder (see Fig.- 6) isremovably sefcured tothe side bars of the swinging frame 4.7 by means ofrods 48 extending through said vbars andthe shuttle feeder and held inposition by cotter pins 49. To the bottom of the shuttle-feeder aresecured strips 50 forming yguides in which slide the gate 51 havingorifices corresponding in number and arrangement to the sh'ellreceptacles'in the shuttle feeder. This'ga'te is in the position 75shown in Fig. 6 when the shuttle feeder is raised against the-eonveyeras shown in Fig. l.; but when theframe 47 is swung down on its pivot 52into a horizontall position, the gate slides in until the holes thereinregister with the receptacles 46, and the shells are then dischargedfrom the receptacles 46l through thefholes in the ate 51 into a shuttle-60v (see Fig. 9) positloned to receive them. 'l 85.*' .The slidingaction lof the. gate is effected I' l by means of al cam slide 53engaging a'pin 54 on the'A gate. The cam-slide is guided'by av strip 55secured to the frame 47 and is connected to a rod 56 pivoted onthe main90' frame. As the frame 47 swings down, it lapproaches the pivot of rod56, thus impart ing to thev latter and. slide 53 a. forward movementrelative to the gate, the cam portion of slide 53 engaging the pin as'the frame 47 reaches v'its lowest position, thereby' sliding the gateas described. When the frame 47 is raised a spr-ing 57 thereon engages apin 58-on the gate and'retu-rns it to its closedposition.

To impartto the various parts the inove' ments described in the properYsequence, I' have. provided mechanismv actuated lfrom a pressure fluidcylinder '61 pivoted on the main frame. The rod 63 of the plunger 62 ofthis cylinder isuconne'eted to a cross-head 64. To this cross-headisattached the swing- 'ing fra-me- 47 an also the links' 65, one-on eachside of the machine. vEach link 65'isA attached' to a llever 66 pivotedat its upper 110 end to a. bracket on the main frame and at its lowerend to a rod`67,' which is attached at its rear end to the cross-head,.25' that actuates the ejectors 23. -f

Pivoted to the base ofthe frame at one side' thereof are levers 68 whoseupper ends have a pin and slot connection with the corresponding lever67. To each -lever 68 is connected a strap 69 passing in oppositedirections part way aroundfand securedto,4 120 a\pulley 70 loose Von theshaft 71,-1towh1eh the sprocket wheels38 are secured.,A The l pulley70carries a springfpressed pawl 72 adapted to successivelyv engagepins73 on a disk 74 secured to the shaft 71. It will be understood thatas the pulley 70 is turned v 'in one direction by means of one of the;straps 69, thepawl '72 dropsbehind one of the pins 73, and the pulley isturned inthe other direction Aby means'of theother'strap 13.0

. 69, thehpawl engages such pin yand turns the shafty "f1 ahalf-revolution; thereby advancing the 4sprocket':chains and thecarriers susof the levers 68, slides-in this guideand enpended therefromAas before described.

'Inorderthat the carrier mechanism shall-V not move beynd the point towhich' -itis positively `moved by the'pawl 72.the` f ollowingmeclianismris Vprovided '(lsee Figs. "1 and 4); cani lever -75 ispivjoted. on a -guide' 7 60 secured to the main frame," One gages thelever .75 at each movement for .advancing l,the carrier and movestherear i' socket 77 in line with pins 78 on the adjacent'sprocket wheel38. T he slide-bar 7 6 is )moved to. itsinner operative position beforethe carrier lactuating movement is coin- .turns the plunger 62, elevatesthe shuttle-- 'feeder 45, retracts the ejectors 23, and ad- Y may bedispensed with and the shells ejected V end of the lever inwardly; i Therear end of the lever is forked to engage a p in on the outerend o-f aslide-bar. 76. The inner end of the slide-bar isprovided withupwardlyextending `fingers forming between them-'a pleted andone of the pins 78bottoms in -the socketi' when-the pawlhasreached the end of its stroke.In the return movement tract. the"slide-bar 76.

The .pressure cylinder 6l' is connected with the source of .power bymeans of a pipe 8O controlled lby a. three-way valve 8l and athrottle'valve 810. I Vhenthe valve turned into oneposition,- pressureis admitted to the cylinder, whereupon the plunger is moved forwardly.Iiithis `movement of the plun yger, the ejectors 23 eject a tier ofshells from` thefeedbox into the carrier lpositioned to receive them andthe shuttle feeder l5 is swung down and itsjeontents discharged intotheshuttle 60.4 In this movement of.

the plunger 62, the carrier is not'operated. VVhen'the' valve 81 ismovedto connect the cylinder 61 'with the exhaust, the .weight 82,connected by a cord 83 .with .the crosshead 64, and the springconnecting thejshuttle feeder `frame with the machine frame 'revancesthe carriers, one of Vwhich discharges its contents intoA the incl inedconveyer 425914: as the shuttle feeder is brought into registrationtherewith.`

The machine above described is designed withaview 'of having all, themechanism on a .single floor. This is ordinarily highlyl desirable. Incases where there is no serinis v objection to the location of thefeed-box on anv upper floor, the intermediate carriers from the`feed-box directlyonto the inclined conveyer. Such an arrangement isillus,- trated in Fig. .9. In this figure the carriers and; theiractuating mechanismv are omitted and the cross-head 25 of the ejectors23 is reciprocate'd-from the cross-headt through the" medium of link 90,interniediately piv' lever 93, andconnecting vrod 94.
